A simple Alarm script written in python for the raspberrypi and a PIR sensor using push notifications over Pushover.net
NOTICE!!!!!!!!!!!! This script has been writed for "Wheezy Raspbian" distribution and actually only works with python 2.7.x. For Python 3, httplib has been replaced with http.client and urlencode has moved to urllib.parse. !!!!!!!!!!!!!!!!!!!
Use Connect the PIR sensor to the Raspberry: http://www.raspberrypi-spy.co.uk/2013/01/cheap-pir-sensors-and-the-raspberry-pi-part-1/
Edit the alarm.ini file, by default the cooldown_time is defined on: 1200 seconds. Ensure that the "app_key" and the "user_key" are assigned correctly.
run the alarm: sudo python alarma.py Close the alarm with Ctrl+C
When a movement is detected a thread is launched to contact with the Pushover server. If the alarm message is sent, the PIR sensor waits a number of seconds (defined in cooldown_time) until is ready again. If the network or the pushover web service fails, the alarm try again with the next movement.
You can program and disable the push notifications by your pushover app.
If your are using a ssh connection, when the ssh session ends, the script exit too. To avoid this you can use crontab, or screen program. $ sudo apt-get install screen Simple use: $ screen (make a new screen on the backgroud) $ sudo python alarma.py Ctrl+a and then push "d" (deatach) Now you can close the ssh and the alarm works on the background. to restore de screen session: $ screen -r More info with screen --help
If you want to start the script when the raspberry boots you can edit the /etc/rc.local file and add this at end /path to your install/alarma.sh & (& runs on background)
/etc/init.d/rc.local start || stop (to start and stop)
